PROCESS FOR MICROCHANNEL PRODUCTION OF COLORED SPHERICAL GRAIN AND MICROCHANNEL PRODUCTION APPARATUS FOR USE THEREIN

摘要

PROBLEM TO BE SOLVED: To provide two-colored spherical particles which are monodisperse colored spherical particles and classified into two colors useful for displays such as characters, graphics and picture displaying and, from the view point of display, furthermore which are reversely indicative with electricity and magnetism and to provide a new manufacturing method and a manufacturing apparatus thereof.;SOLUTION: The micro-channel-manufacturing method comprises the steps of transferring into the first micro-channel the colored material continuous phases each with different hues 6a and 6b dispersed in a fluid dispersion medium containing a polymerizable resin component, with the colored material continuous phases each with different hues 6a and 6b and a spherically particulate dispersed phase 7 being respectively in the relationship of an O/W or a W/O type, then discharging continuously or intermittently in the spherically particulate dispersed phase 7 flowing in the second micro-channel 2 at a specified (rate) flow F2 (ml/h), and then curing the polymerizable resin component in the colored material continuous phases of spherical particles with two hues to thereby form a colored spherical polymer particles, and the micro-channel-type manufacturing apparatus is used therefor.;COPYRIGHT: (C)2004,JPO&NCIPI
